Bush roller from sintered iron alloy
Sintered Bushes Briefing:
-----------------------------------------------------------------------------------------------------
Sintering Part is made by bronze or iron / stainless steel powder, mold pressed under high pressure and then sintered under high temperature, and oil is soaked into the homoeneously spreaded tiny pores of the metal under vacuum. Sintered bushing is widely used for domestic electric equipments, electirc tools, woven machines, chemical engineering machines, automobiles industry, etc. Quality standard based on JIS; DIN; GB; MPIF, etc.

Sintered Bushes Advantage:
-----------------------------------------------------------------------------------------------------
1. With lower wear rate and long lifetime.
2. Provides maintenance free operation & Dry working circustmance.
3. Suited for high static and dynamic load.
4. With low and smoothly coefficient of friction and without stick-slip effects.
5. Suitable for dirty, impact and edge load.
6. Better thermal conductivity property.
